Wignacourt Aqueduct

The Wignacourt Aqueduct is a 17th-century aqueduct in Malta, which was built by the Order of Saint John to carry water from springs in Dingli and Rabat to the newly built capital city Valletta. The aqueduct was carried through underground pipes and over arched viaducts across depressions in the ground.

The first attempts to build the aqueduct were made by Grand Master Martin Garzez in 1596, but construction was suspended before being continued in 1610. The watercourse was inaugurated five years later on 21 April 1615. Several engineers took part in the project, including Bontadino de Bontadini, Giovanni Attard and Natale Tomasucci. The aqueduct was named after Grand Master Alof de Wignacourt, who partially financed its construction.
